Eutrophication of U.S. freshwaters: analysis of potential economic damages.
Human-induced eutrophication degrades freshwater systems worldwide by reducing water quality and altering ecosystem structure and function. We compared current total nitrogen (TN) and phosphorus (TP)Expand
Suggested classification of stream trophic state: distributions of temperate stream types by chlorophyll, total nitrogen, and phosphorus
The proposed trophic boundaries for streams generally include a broader range of values in the mesotrophic range than conventional criteria for lakes, reflecting the greater variance in streams. Expand
Control of Nitrogen Export from Watersheds by Headwater Streams
A comparative 15N-tracer study of nitrogen dynamics in headwater streams from biomes throughout North America demonstrates that streams exert control over nutrient exports to rivers, lakes, andExpand
Stream denitrification across biomes and its response to anthropogenic nitrate loading
It is demonstrated that excess nitrate in streams elicits a disproportionate increase in the fraction of nitrate that is exported to receiving waters and reduces the relative role of small versus large streams as nitrate sinks. Expand
Inter‐biome comparison of factors controlling stream metabolism
SUMMARY 1. We studied whole-ecosystem metabolism in eight streams from several biomes in North America to identify controls on the rate of stream metabolism over a large geographic range. The streamsExpand
Life on the Edge: The Ecology of Great Plains Prairie Streams
Abstract Great Plains streams are highly endangered and can serve as model systems for studying disturbance ecology and related issues of resistance and resilience in temperate freshwaters. TheseExpand
Nitrogen and phosphorus relationships to benthic algal biomass in temperate streams
Knowledge of factors limiting benthic algal (periphyton) biomass is central to understanding energy flow in stream ecosystems and stream eutrophication. We used several data sets to determine howExpand
Nutrient limitation of epilithic and epixylic biofilms in ten North American streams
The results show that biomass responses to nutrient addition by the heterotrophic and autotrophic components of the epixylic biofilm were different, though both experienced the same stream nutrient conditions. Expand
Inter-regional comparison of land-use effects on stream metabolism
SUMMARY 1. Rates of whole-system metabolism (production and respiration) are fundamental indicators of ecosystem structure and function. Although first-order, proximal controls are well understood,Expand
Freshwater Ecology: Concepts and Environmental Applications
This book is a general text covering both basic and applied aspects of freshwater ecology and serves as an introduction to the study of lakes and streams, with explanations of complex contemporary concepts in freshwater ecology described to promote understanding. Expand
